In vitro study of effectiveness of plant extracts against rhizoctonia solani causing sheath blight disease on rice (Oryza sativa L.) / Nur Maryam Mohamed

Rice is an important cereal crop affected by various fungal, bacterial and virus diseases. Sheath blight disease caused by Rhizoctonia solani is one of the destructive disease under favourable weather conditions in rice growing areas that ultimately causes high yield losses. The initial symptoms are...

Sheath blight disease caused by Rhizoctonia solani is one of the destructive disease under favourable weather conditions in rice growing areas that ultimately causes high yield losses. The initial symptoms are the formation of irregular or oval greenish grey spots on the leaf sheath. The symptom of disease was observed by using pathogenicity test.

The antifungal effect of two plant extract which are Aloe vera (Aloe) and Chromolaena odorata (Siam weed) against the pathogen R. solani was evaluated by dual culture method. All plant extracts showed effective results with a various degree of antimicrobial effect at the different concentration which are 0%, 25%, 50% and 100%. Aloe vera shows strong fungitoxicity at 25% and 100% concentration with 88.00% mean inhibition fungus growth. While, C. odorata showed strong fungitoxicity at 100% with 79.33% mean inhibition.
